Focusing on selected social aspects of multiple offshore use, this paper presents a short overview of recent research results on the potential and problems of wind farm-mariculture integration in the German Bight. Far from falling, the actual capital costs per MW of capacity to build new wind farms increased substantially from 2002 to about 2015 and have, at best, remained constant since then. Large wind farms farther off the coast pose high expectations because of higher average wind speeds and hence greater wind energy yield (in terms of megawatts per capital). Finally, we employ simulations using realistic deployment and traffic and advanced propagation and collision models to characterize these two approaches' feasibility and packet delivery probability numerically when implemented over LoRaWAN mMTC technology. The development of repair materials developed by Sika Germany GmbH and novel application and assessment procedures developed by Muehlhan AG are at the centre of the project.
